Again on JEditorPane printing, please help me

Question

Hi everybody,
first of all excuse me if I write again about an already discussed topic,
but I still haven't found a good solution for it.
I have a JEditorPane that I use to render HTML documents, and I need
to be able to print the contents.
I then created my PrintableEditorPane class that implements Printable
add the following print() method:
public int print(Graphics g, PageFormat fmt, int index) throws PrinterException
        Graphics2D g2d = (Graphics2D) g;
        // Set default foreground color to black
        g2d.setColor(Color.black);
        // For faster printing, turn off double buffering
        RepaintManager.currentManager(this).setDoubleBufferingEnabled(false);
        // Get size of document
        Dimension d = getSize();
        double panelWidth = d.width; // Width in pixels
        double panelHeight = d.height; // Height in pixels
        double pageWidth = fmt.getImageableWidth(); // Width of printer page
        double pageHeight = fmt.getImageableHeight(); // Height of printer page
        int totalNumPages = (int) Math.ceil(panelHeight / pageHeight);
        // Make sure not print empty pages
        if (index >= totalNumPages)
            return Printable.NO_SUCH_PAGE;
        // Shift Graphic to line up with beginning of print-imageable region
        g2d.translate(fmt.getImageableX(), fmt.getImageableY());
        // Shift Graphic to line up with beginning of next page to print
        g2d.translate(0f, -index * pageHeight);
        // Repaint the page for printing
        paint(g2d);
        return Printable.PAGE_EXISTS;
}Everything works quite fine, with the exception that if text spans on
multiple pages, it can happen that the bottom part of the last line in
a page is printed in the next one.
I found that this topic occurs rather frequently in the forum, so I changed
the code with the following one, taken from the Internet:
public int print(Graphics g, PageFormat fmt, int index) throws PrinterException
        Graphics2D g2d = (Graphics2D) g;
        // Set default foreground color to black
        g2d.setColor(Color.black);
        // For faster printing, turn off double buffering
        RepaintManager.currentManager(this).setDoubleBufferingEnabled(false);
        // Shift Graphic to line up with beginning of print-imageable region
        g2d.translate(fmt.getImageableX(), fmt.getImageableY());
        View rootView = getUI().getRootView(this);
        if (index > currentPage)
            currentPage = index;
            pageStartY += pageEndY;
            pageEndY = g2d.getClipBounds().getHeight();
        g2d.translate(g2d.getClipBounds().getX(), g2d.getClipBounds().getY());
        Rectangle allocation = new Rectangle(0, (int) -pageStartY, getWidth(), getHeight());
        if (printView(g2d, allocation, rootView))
            return Printable.PAGE_EXISTS;
        else          
            currentPage = -1;
            pageStartY = 0.0;
            pageEndY = 0.0;
            return Printable.NO_SUCH_PAGE;
protected boolean printView(Graphics2D g2d, Shape alloc, View view)
        boolean pageExists = false;
        Rectangle clip = g2d.getClipBounds();
        Shape childAlloc;
        View childView;
        if (view.getViewCount() > 0)
            for (int i = 0; i < view.getViewCount(); i++)
                childAlloc = view.getChildAllocation(i, alloc);
                if (childAlloc != null)
                    childView = view.getView(i);
                    if (printView(g2d, childAlloc, childView))
                        pageExists = true;
        else
//  I
            if (alloc.getBounds().getMaxY() >= clip.getY())
                pageExists = true;
//  II
                if ((alloc.getBounds().getHeight() > clip.getHeight()) && (alloc.intersects(clip)))
                    System.out.println("Calling view.paint()... (1)");
                    view.paint(g2d, alloc);
                else
//  III
                    if (alloc.getBounds().getY() >= clip.getY())
                        if (alloc.getBounds().getMaxY() <= clip.getMaxY())
                            System.out.println("Calling view.paint()... (2)");
                            System.out.println(view.getClass().getName());
                            System.out.println(view.getElement().getName());
                            view.paint(g2d, alloc);
                        else
//  IV
                            if (alloc.getBounds().getY() < pageEndY)
                                pageEndY = alloc.getBounds().getY();
        return pageExists;
} Now pagination is handled correctly, but a new problem arises: table
borders are not printed at all, and this topic too is not new in the forum.
So I made some investigations that you can see from the println() in the
code and I found out that all the views are of class InlineView, that is returned
from HTMLEditorKit when an element with name "content" is found.
Now the real questions: why don't I get the real views hierarchy of the HTML
document, and how can I solve my problem?
Many thanks to anyone who will like to help me.
Matteo.

Hello, and thanks for all the great help so far in this thread! I have implemented the above code, and it seems to work great, except for one thing. It always prints the first page twice. My print method is exactly as listed above. Here is my printView method:
protected boolean printView(Graphics2D g2d, Shape alloc, View view)
               boolean pageExists = false;
               Rectangle clip = g2d.getClipBounds();
               Shape childAlloc;
               View childView;
               //System.out.println("View name = " + view.getElement().getName());
               if (view.getViewCount() > 0 && !view.getElement().getName().equalsIgnoreCase("td"))
                    for (int i = 0; i < view.getViewCount(); i++)
                         childAlloc = view.getChildAllocation(i, alloc);
                         if (childAlloc != null)
                              childView = view.getView(i);
                              if (printView(g2d, childAlloc, childView))
                                   pageExists = true;
               else
//          I
                    if (alloc.getBounds().getMaxY() >= clip.getY())
                         pageExists = true;
//          II
                         if ((alloc.getBounds().getHeight() > clip.getHeight()) && (alloc.intersects(clip)))
                         //     System.out.println("Calling view.paint()... (1)");
                              view.paint(g2d, alloc);
                         else
//          III
                              if (alloc.getBounds().getY() >= clip.getY())
                                   if (alloc.getBounds().getMaxY() <= clip.getMaxY())
                              //          System.out.println("Calling view.paint()... (2)");
                              //          System.out.println(view.getClass().getName());
                              //          System.out.println(view.getElement().getName());
                                        view.paint(g2d, alloc);
                                   else
//          IV
                                        if (alloc.getBounds().getY() < pageEndY)
                                             pageEndY = alloc.getBounds().getY();
               return pageExists;
     }Can anyone see why it would print the first page twice every time?
Thanks for you help!
